meaning Fluro's are filled with Argon gas, the purpose for it in these bulbs is to become
heated and increase the gas pressure. Gas pressure = more lumens / watt.. In MH, MV, HPS
and LPS it is used for the same thing, but some of it also get ionized and adds to the
light spectrum, so it is a duel purpose in these bulbs.

Boomer, please, do not dissappoint me in your wisdom and correct yourself, please :-))
From above statement we can read that gases in the fluorescent tubes do not
get ionized, which is not true to my knowledge. They do get ionized and they
emit UV light, which is turned into visible rays of light by the phosphors
mixture on the internal surface of the tubes... The ionization process is started
by the high voltage surge when the bulb is powered on. Starting voltage is about 600V
and depends highly on the lenght of the tube and the temperature of filaments on both
ends. Traditional tubes had filaments heated to support tube starting with lowered
voltages. The new designs have rather high voltage and no heating.
The bottom line: If you use UV-transparent glass
type to make the tube and do not use phosphors you would get the UV fluorescent tube.
It is not the pressure which generates light. It is UV rays of ionized gas induce
secondary emission from phosphors on the tube surface in the visible part of spectrum.
The pressure may influence other factors, but the pressure itself does not
generate light - sorry Boomer :-)

And to much pressure can make the
bulbs go Kaboom, such as screwing a 175 watt into a 250 and a 400 for sure.

Exactly - The increased risk of glass shattering is another reason against overdriving.
I should mentioned this on my list before :-)

p.s. Petition to The King Marc: do not interprete my message as aggressive again :-))))
